Re: Initial Public Offering

Ladies and Gentlemen:

This letter is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into by and between Orbit Acquisition Corp., a Delaware corporation (the “Company”) and JPMorgan Securities Inc., as representative of the several underwriters (the “Underwriters”), relating to an underwritten initial public offering (the “Offering”) of 25,000,000 of the Company’s units (the “Units”), each comprised of one share of the Company’s common stock, par value $0.0001 per share (the “Common Stock”), and one warrant exercisable for one share of Common Stock (each, a “Warrant”). The Units sold in the Offering will be listed and traded on the American Stock Exchange pursuant to a Registration Statement on Form S-1 and prospectus (the “Prospectus”) filed by the Company with the Securities and Exchange Commission. Certain capitalized terms used herein are defined in paragraph [9][10] hereof.

In order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the Offering and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned [officer] [director] hereby agrees with the Company as follows:

1.

The undersigned also acknowledges and agrees that he or she will not have any conversion rights [with respect to the shares of Founders’ Common Stock owned or] with respect to any shares of Common Stock acquired in or following the Offering by the undersigned.

[Include for independent directors only: (c) The undersigned hereby waives any right, title, interest or claim of any kind in or to any distributions of the Trust Account as a result of any liquidation of the Company with respect to his or her shares of Founders’ Common Stock. The undersigned hereby waives any claim the undersigned may have in the future against the Trust Account, and will not seek recourse against the funds held in or distributed from the Trust Account prior to an Initial Business Combination, in either case on account of, or arising out of, any contracts or agreements with the Company.]

2. The undersigned [officer] [director] hereby agrees that in the event that the Company fails to consummate an Initial Business Combination within 24 months after the date of the final Prospectus relating to the Offering (or within any Extension Period), the undersigned shall take all reasonable steps to (a) cause the Trust Account to be liquidated and distributed to the holders of Common Stock purchased in the Offering as soon as reasonably practicable and (b) cause the Company to be dissolved and liquidated as soon as reasonably practicable.
